Process for rotary die cutting of reclaimed polyester

Abstract

A method for rotary die cutting. The method may include providing, to an accumulator, an input comprising a melt. The method may include processing, by the accumulator utilizing a set of rolls, the melt to form a sheet of material. The method may include providing, from the accumulator, the sheet of material to a dandy roll. The method may include providing, from the dandy roll, the sheet of material to a rotary die. The method may include cutting, by the rotary die, a product from the sheet of material. The method may include providing, from the rotary die, the product to a stacker.

1 . A method for rotary die cutting, the method comprising:
 providing, to an accumulator, an input comprising a melt;   processing, by the accumulator utilizing a set of rolls, the melt to form a sheet of material;   providing, from the accumulator, the sheet of material to a dandy roll;   providing, from the dandy roll, the sheet of material to a rotary die;   cutting, by the rotary die, a product from the sheet of material; and   providing, from the rotary die, the product to a stacker.   
     
     
         2 . The method of  claim 1 , wherein the input is provided from a reactor. 
     
     
         3 . The method of  claim 1 , wherein the input is provided from an extruder. 
     
     
         4 . The method of  claim 1 , wherein the input comprises post-consumer flake or resin polyethylene terephthalate (PET) or virgin flake or resin PET. 
     
     
         5 . The method of  claim 1 , further comprising:
 stacking, by the stacker, the product with one or more other products; and   at least one of:
 processing the product after the product is stacked, 
 including the product into one or more other products, or 
 packaging the product. 
   
     
     
         6 . The method of  claim 1 , the method further comprising:
 providing, from the rotary die, scrap resulting from cutting the product from the sheet of material to a skeleton roll.   
     
     
         7 . The method of  claim 6 , further comprising:
 re-processing the scrap into a new input for provisioning to the accumulator.   
     
     
         8 . The method of  claim 1 , wherein the accumulator is configured to cool the melt to a temperature where the product can be cut from the sheet of material. 
     
     
         9 . The method of  claim 1 , wherein the dandy roll is configured to allow for sudden speed changes in the sheet of material while maintaining tension of the sheet of material. 
     
     
         10 . A system for rotary die cutting, comprising:
 an accumulator to receive an input comprising a melt and process the input utilizing a set of rolls to form a sheet of material;   a dandy roll configured to receive the sheet of material from the accumulator;   a rotary die configured to receive the sheet of material from the dandy roll and to cut a product from the sheet of material; and   a stacker configured to receive the product from the rotary die.   
     
     
         11 . The system of  claim 10 , further comprising:
 a reactor configured to provide the melt as the input.   
     
     
         12 . The system of  claim 10 , further comprising:
 an extruder configured to provide the melt as the input.   
     
     
         13 . The system of  claim 10 , wherein the input comprises post-consumer flake or resin polyethylene terephthalate (PET) or virgin flake or resin PET. 
     
     
         14 . The system of  claim 10 , further comprising:
 a skeleton roll configured to receive, from the rotary die, scrap resulting from cutting the product from the sheet of material.   
     
     
         15 . The system of  claim 10 , wherein the accumulator is further configured to cool the melt to a temperature where the product can be cut from the sheet of material. 
     
     
         16 . The system of  claim 10 , wherein the dandy roll is configured to allow for sudden speed changes in the sheet of material while maintaining tension of the sheet of material. 
     
     
         17 . The system of  claim 10 , wherein the stacker is configured to stack the product with one or more other products. 
     
     
         18 . The system of  claim 10 , further comprising:
 one or more elements to:
 process the product after the product is stacked, 
 include the product into one or more other products, or 
 package the product. 
   
     
     
         19 . The system of  claim 10 , further comprising:
 a device that comprises computer-readable instructions stored on a computer-readable medium, and one or more processors, wherein the instructions, when executed by the one or more processors, cause the device to control the operations of the accumulator, the dandy roll, the rotary die, or the stacker.   
     
     
         20 . A device, comprising:
 computer-readable instructions stored on a computer-readable medium, and one or more processors, wherein the instructions, when executed by the one or more processors, cause the device to control one or more of an accumulator, a dandy roll, a rotary die, or a stacker to:   receive an input comprising a melt;   process, utilizing a set of rolls, the melt to form a sheet of material;   provide the sheet of material to a dandy roll;   provide the sheet of material to a rotary die;   cut a product from the sheet of material; and   provide the product to the stacker.
